Rocket In The Sky Plus Accident

Lendl says...

It was not a test launch. It was an instantaneous launch just after sunset to launch 10 satellites. The clock on the dash cam must not be set to local time.

"SpaceX is targeting launch of Iridium-4 from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California. The instantaneous launch window is at 5:27 p.m. PST on Friday, December 22"


https://spaceflightnow.com/2017/12/23/spacex-launch-dazzles-delivering-10-more-satellites-for-iridium/

"The two-stage, kerosene-fueled rocket climbed into the rarefied upper atmosphere a few minutes following liftoff shortly after sunset at 5:27:34 p.m. PST (8:27:34 p.m. EST; 0127:34 GMT) from Space Launch Complex 4-East Vandenberg Air Force Base northwest of Los Angeles.

The Falcon 9 left a brilliant white plume of exhaust in its wake, catching rays of sunshine as it soared above the stratosphere. The ever-expanding plume left a teardrop-shaped mark in the sky, prompting countless social media posts from rush hour drivers and others who happened to catch an unexpected glimpse of the rocket’s trip to space."

at first I thought, "why don't they do these test launches late at night when fewer people are out on the roads?" then I saw the timestamp at the bottom was ~1:30am.

Accident was here: Google Maps
Highway 10, between LA and Phoenix.

A Riddle (Blog Entry by dystopianfuturetoday)

messenger says...

@Boise_Lib

My first answer is definitely wrong because it assumes that the increased displacement of the boat due to the anchor's mass is equal to the displacement by the anchor's volume when it enters the water. This is demonstrably false, as a 5kg lead anchor would cause a boat to displace as much water as a 5kg iridium anchor in the same boat, but the lead anchor would displace about twice as much water as the iridium anchor when thrown in the water.

Let's say my anchor is iridium, and is massive enough it almost sinks the boat. The boat is now displacing much more water than the anchor will when I throw it overboard, so the answer is the water will fall. In my thought experiment, I now decrease the density of my imaginary anchor and increase its size such that the boat is always just barely afloat. When I toss the anchor overboard, the water will fall less and less, but as long as the boat is floating (not much of a boat if it doesn't float) and the anchor alone is denser than water (not much of an anchor if it's not denser than water, I believe the anchor will always cause the boat to displace more water in the boat than outside the boat. I'm sure I could use limits to prove this, but I'm just going to assume I'm right without doing the calculus. So my new answer is: the water will always fall.

Thanks for the mental exercise.

(How did I do?)

The point is that gold has insufficient actual USES to fall back on as a basis for its high value.


It doesn't have to be useful for consumption, it is useful as money. Do you understand what money is and why it's an important good in a modern economy. Do you understand that people can demand and want something for this purpose rather than to consume it or play with it? Do you understand that that's exactly what happened with gold when people were left to their own devices?

>> ^jwray:
The price of gold is subject to the volatile whims of the people, and has fluctuated a great deal over the last 100 years.


The value of the dollar relative to other currencies has fallen 70% in the last ten years, and 300% relative to gold. That's not volatile? See, your mistake is you're looking at the value relationship in the wrong way. You see the dollar maintaining its value and everything else flailing wildly against it. Instead, the dollar and people's confidence in it is what's flailing wildly. Look at a chart comparing gold to oil (both priced in dollars) the last thirty years - almost completely flat. If gold was money, gas prices would have gone nowhere.

http://www.kitco.com/ind/saville/may022006.html

Also interesting to note from this chart is what the price for both was in ~1971. Guess what happened in 1971 that caused the chart to start moving up for thirty years? Nixon scratched the bretton woods semi-gold standard, removing the last link of the dollar to gold. A nation that built its country on gold and became the reserve currency of the world on gold, inflated heavily in the 60s to finance pointless activities like Vietnam, The War on Poverty, the Great Society. It got to a point where gold reserves were far less than the debt owed to foreigners by 1971, the equivalent of an fractional reserve bank run. Those foreigners began calling in the debt, and rather than stop inflating and cutting a deal, Nixon got on a podium and broke the contract because it wasn't in "our best interest." Just like that. It later became permanent. Full fiat. Now there was NOTHING backing the dollar but confidence in its scarcity which is controlled by government.

We currently lie about inflation and pay foreigners back in devalued dollars, probably more devalued than the interest return on those bonds, but the CPI hides it with hedonics adjustment, substitution, and geometric weighting added during the Clinton years. The bond market is the last major bubble in the U.S. economy.

But since we libertarians understand human behavior and the nature of government, it meant inevitable hyperinflationary collapse. Because like every other fiat currency in history, it will be debased by its spendthrift government and the citizens will stand by and let it happen because they are exactly like you: ignorant of economics and eternally trustful of government. That's why our forefathers tried to illegalize fiat in the constitution after they saw the continental dollar hyperinflated.

Platinum, Iridium, and Silver would work just as well as gold. But if a great depression comes I would rather have a stockpile of wheat than a stockpile of gold.


How long is that wheat going to last before spoiling? Where are you going to store it? How are you going to carry it around and pay people with it? What if someone already has enough wheat and they want berries, and the guy who has berries doesn't want wheat either, he wants leather? You're reducing yourself to barter. You can't run a modern economy that way.

>> ^jwray:
Under the current federal reserve system, if they set interest rates properly and avoid excess printing, inflation can be kept below 2%. Theoretically, if the fiat money system is done properly, it can be more stable in value than a gold-backed currency.


Welcome to today's powerful neo-Keynesian economic circles. Centralized control curriculums, a sexy interventionist theory financed by the benefactors of inflation, overrides history, human behavior, and all rational skepticism. The benevolent dictator argument, in its truest form. The fallacy that because its possible to have a benevolent dictator more efficient than any system that divides powers and makes it impossible for one man to destroy a country, that we should institute that system. No different than the Federal Reserve, in my opinion. They are THE ROOT CAUSE of most of our problems today. Right down to health care costs, another victim of inflation and HMO legislation, which the socialists are again trying to blame the free market on to build up more socialism. It all comes back to what system preserves wealth, and this ain't it.

The Euro is doing just fine with an inflation rate of 1.8%.


Measured by whom, and for how long? We could have said the same thing years ago. Will hyperinflation occur under you or your children or your grandchildren? Who knows, right? All you know is it's happened before in Europe, now it's just more centralized so all countries will be affected when it happens. Congrats.

Do you understand why we're fucked now? Why it's hopeless, why I bury my head every time someone calls Ron Paul a kook. You are just one of 200 million people I have to convince in this country, and it took me five hours with you and I probably still didn't make a dent.

In fact, here's the hilarious trickery of Keynesian economics. China holds over 1 trillion U.S. dollars in their reserves. That's right, we borrow from them, they're the largest creditor nation and we're the largest debtor (we actually used to be the largest creditor, that's how far we've fallen). But the reason they do it: they falsely believe that Americans consuming their products is driving their economy. In the beginning, this was true because they did have a legitimately weak currency relative to ours. But now things are different. They're INTENTIONALLY debasing their money to keep trying to grow this way even though they don't need to: currency appreciation would allow them to consume their own products without us. So they are intentionally devaluing their currency by inflating and buying up our bonds, on a grand scale, essentially paying Americans to consume their exports even though they can only afford them because of these payments. Insanity! If they ever figured this out, the bond bubble will pop. Even the ECB is not hiking rates when they should be. The world has been fooled into thinking that the American consumer is responsible for all their growth and is fearful of letting it collapse. Consumption over production, putting the cart before the horse, the mainstay of Keynesian thinking.

The price of gold fluctuates, as anybody can manipulate the market. We could see 10% inflation one year and 10% deflation the next year.
